The rain has passed, and the snow on the black land has not disappeared. In Heping Village, Lishu Township, Huanan County, Jiamusi City, Heilongjiang Province, the greenhouse base is in full swing. Sun Bin, the representative of the National People's Congress and the chairman of Hongyuan Rice Professional Cooperative in Huanan County, Heilongjiang Province, and many farmers are sorting out agricultural materials to seize the favorable opportunity of the weather to warm up and carry out the work of preparing for spring cultivation. "My biggest concern is related to rural areas, agriculture and farmers." Sun Bin has been actively performing his duties since he was elected to the National People's Congress in 2013, offering advice and suggestions for the development of "agriculture, rural areas and farmers". Heilongjiang is a major agricultural province in China. There are 192 administrative villages in Huanan County, and Sun Bin has visited more than 120. During his career in the past 10 years, he has submitted 185 representative proposals, covering black land protection, straw returning, agricultural machinery subsidies, seed industry development, grain storage and other aspects. In his view, every proposal and every speech carried the dreams and aspirations of the farmers' brothers. In the spring ploughing season, some farmers secretly burned straw in the open air in order to seize the farming season. "When I drive on the road, I often see fire in the fields beside the road. It's really 'hot eyes and choking nose' when I get close. It's very uncomfortable. Burning straw indiscriminately not only pollutes the air, but also has fire risk." Sun Bin said. However, there are a large number of corn, rice and other crop stalks in Heilongjiang Province. On the one hand is the ban on environmental protection, and on the other hand is the season of spring farming. Straw lying in the field has become a "heart disease" of farmers. "Only the combination of blocking and dredging can make the 'fire dragon' completely disappear from the field." In 2018, Sun Bin put forward the "Suggestions on Increasing the Comprehensive Utilization of Straw Returning to Field" at the National Two Sessions, including increasing the research and development of straw returning agricultural machinery equipment, and providing appropriate subsidies. This suggestion has been highly valued by relevant national ministries and commissions and Heilongjiang Province. Heilongjiang Province proposes to further increase the support for the comprehensive utilization of straw, introduce and improve relevant policies, cultivate and improve the socialized service system, and continuously improve the development level of agricultural industrialization. In recent years, thanks to a series of favorable policies, the straw that used to be "nowhere to lay" is "turning waste into treasure". Heilongjiang Province has actively promoted the fertilizer, feed, base material, raw material and fuel of straw. Some regions and counties have promoted the pilot of comprehensive utilization of straw, and other regions have explored the implementation of full straw return to the field. The black land known as "the giant panda in the cultivated land" has been nourished and protected. Sun Bin said that to ensure food security, we must firmly hold the red line of 1.8 billion mu of cultivated land, effectively curb the "non-agricultural" of cultivated land and prevent the "non-grain" of cultivated land. "A few years ago, some fields in the countryside were idle and some good fields were overgrown with weeds." Sun Bin was very sad to see such a scene during a visit to the village. "In order to solve the problem of 'non agricultural' and 'non grain', the first thing to be solved is to guide farmers to be careful and improve their quality." Based on the actual survey, Sun Bin put forward the "Suggestions on Strengthening the Construction of Modern Seed Industry Upgrading Project to Promote the Innovative Development of Modern Seed Industry" and "Suggestions on Realizing the Agricultural Modernization of Important Commodity Grain Production Base", which were adopted by relevant national ministries and commissions, Relevant policies should be issued in time.
